摘要 |
The bags are produced on a form-fill seal machine operating horizontally or vertically. Zipper strips ( 16 ) are initially attached to a continuous web ( 12 ) which is subsequently formed into a continuous run of bags having end seals ( 20 ) and a back seal ( 18 ). The continuous run is separated into individual bags and the zipper strips finally attached to the bag walls by application of heat and/or pressure by a belt sealer ( 26 ) operating in a direction perpendicular to that of movement of the continuous web. |
